A white space device (WSD) is a communications device that uses the unused spectrum in the television broadcast band (the "white spaces") for wireless communication.
WSDs are similar to other unlicensed devices, such as Wi-Fi routers, that operate in the unlicensed 2.4 GHz and 5 GHz bands. However, WSDs have the potential to operate in a much larger swath of spectrum than unlicensed devices because they can take advantage of the unused spectrum in the TV broadcast band.
The use of white space spectrum for wireless communication was first proposed in the early 2000s as a way to increase the efficiency of spectrum usage. The concept was initially met with some opposition from the broadcasting industry, but the FCC eventually decided to allow the use of white space spectrum for unlicensed devices.
In 2010, the FCC released the first set of rules for white space devices. These rules allowed for the operation of devices in the TV broadcast band on a unlicensed basis.
Since then, a number of companies have released white space devices, and the technology is being used in a variety of applications, such as rural broadband, enterprise networking, and smart city applications. What is TV white space technology? TV white space technology refers to the use of unused frequencies in the broadcast television spectrum. These frequencies are typically unused in urban areas, but can be used in rural areas where there is less broadcast traffic. This technology can be used to provide wireless broadband internet access, as well as other wireless services. What is white space in radio advertising? In radio advertising, white space refers to the unused portions of the radio spectrum that are not being utilized by licensed broadcasters. This unused spectrum can be used for a variety of purposes, including two-way radio communications, data transmissions, and other unlicensed uses. While the term "white space" is often used to refer to the unused spectrum in general, it can also specifically refer to the portions of the spectrum that are specifically reserved for unlicensed use.
What are the applications of TV white space?
TV white space is the unused spectrum in the broadcast television bands. It can be used for a variety of applications, such as providing broadband Internet access, delivering wireless video and audio, and connecting devices in the Internet of Things.
One potential application of TV white space is to provide broadband Internet access to rural or underserved areas. TV white space technology can extend the reach of existing broadband infrastructure, providing an alternative to expensive and difficult-to-deploy fiber optic solutions.
Another application of TV white space is to provide wireless video and audio. This could be used to deliver television or radio programming to areas without a wired connection, or to provide a wireless alternative to cable or satellite TV.
TV white space can also be used to connect devices in the Internet of Things. By using TV white space to connect devices, manufacturers can create products that are not limited by the range of traditional wireless technologies. This could enable a whole new class of smart and connected devices.
How fast is TV White Space Internet?
TV White Space Internet is a new technology that utilizes unused television spectrum to provide high-speed Internet access. Because it uses spectrum that is already allocated for television broadcasting, TV White Space Internet does not require any new spectrum allocations.
TV White Space Internet can provide speeds of up to 10Mbps, which is on par with other fixed broadband technologies such as DSL and cable. However, TV White Space Internet is still in the early stages of development and deployment, so its actual speeds may vary depending on the specific deployment.
What frequency is white space? There is no definitive answer to this question as white space can refer to any unused portion of the electromagnetic spectrum. In the United States, the Federal Communications Commission (FCC) has designated certain frequencies as white space, which are available for unlicensed use. These frequencies vary depending on the location, and are typically in the UHF or VHF range.
